With the capability of MgAl2O4 spinel {111} nano-facets in
stabilizing small Rh, Ir and Pt particles, bimetallic Ir-Pt catalysts on
the same support were investigated, aiming at further lowering the
catalyst cost by substituting expensive Pt with cheaper Ir in the bulk.
Small Pt-Ir nano-alloy particles (
